SMS-DIRECT Multi-Directional Sound Masking Speaker

The SMS-DIRECT speaker mounts on a U-bracket and suspends in the plenum, or hangs off walls or structural columns, firing sound upward for diffuse masking in standard ceilings or downward in very high plenums and exposed-structure designs. This multi-directional speaker covers a wide range of ceiling conditions and office layouts for optimal speech privacy.

  • Sturdy u-bracket aims the speaker up-firing or down-firing to suit any ceiling height and office design
  • Works well in standard plenums, but specially designed to excel in high or exposed-structure ceilings
  • 13 cm full-range driver for smooth, uniform sound masking
  • Fireproof ABS enclosure, available in white or black
  • Runs on 25 V lines with simple screw-terminal wiring
  • One flexible sound masking speaker for varied ceiling conditions and interior design attributes on a single project

How Sound Masking Speakers Are Powered & Controlled

Multizone sound masking controllers

Multizone Sound Masking Controllers

The brains of your sound masking system. Controllers generate the broadband masking signal and coordinate it across speaker groups, delivering the right level to each office zone. They double as multi-input amplifiers for paging and ambient music.

Sound masking system management software

System Management Software

A building automation interface, but specially developed for easy sound masking system management. Design, commission, and run the system from one graphical view of every component and wire, laid over the office plan. Adjusting volume and EQ for any masking or paging zone takes seconds.

Adaptive Sound Masking Beats Static, Timer-Based Systems

Traditional systems raise and lower masking on a fixed timer, guessing at how busy a space will be. Adaptive sound masking measures the real ambient noise and adjusts continuously, so speech privacy and comfort stay consistent whether the floor is packed or empty, with no one touching a dial.
